The Senate Investigations Subcommittee released last week the Levin-Coburn Report on the financial crisis, which Senator Levin's press release describes thus:

Concluding a two-year bipartisan investigation, Senator Carl Levin, D-Mich., and Senator Tom Coburn M.D., R-Okla., Chairman and Ranking Republican on the Senate Permanent Subcommittee on Investigations, today released a 635-page final report (PDF, 6MB) on their inquiry into key causes of the financial crisis. The report catalogs conflicts of interest, heedless risk-taking and failures of federal oversight that helped push the country into the deepest recession since the Great Depression.
